What is Thermal Imaging?
Thermal imaging is the detection and measuring of radiation in the infrared spectrum being emitted from an object with the use of thermographic cameras or scopes. These infrared imaging systems produce thermal video or still images (thermograms) using color differences to point out the various temperature points of an object from hot to cold levels. Since the amount of radiation increases with higher temperatures, warm spots will stand out from colder spots on the thermal image. And being thermal imaging cameras do not need light to operate, they can detect objects in total darkness or in daylight.
Thermal imaging can detect man or best hundreds of yards away in the darkness, making it a vital tool for promoting safety in hunting.
There are typically two types of thermal imaging systems; cooled and uncooled. Cooled thermal imaging sensors feature the best resolution and operability of the two types of thermal sensors. They can read differences as small as .2 degrees F from more than 1,000 feet away. The only drawbacks of this type of sensor are that they are very expensive and do not stand up well to being bumped around. The uncooled thermal imaging sensors, which represent the hunting scopes on our site, don’t have quite the sensitivity of cooled models but they are very inexpensive in comparison and rugged enough to withstand heavy use. They operate at room temperature, so they do not need to have the extra cryogenic cooling systems. The thermal imaging scopes we offer will certainly hold up to repeated use out in the wilderness.
